Celestial Star Globe – Transparent Sphere – 12″

A celestial globe is a hands-on model of the night sky, designed to show how stars appear from Earth. It consists of:

• An Earth sphere: A 4-inch globe representing our planet, marked with continents, that rotates to simulate Earth’s daily spin.
• A star sphere: A larger, 12.5-inch transparent sphere surrounding the Earth, displaying constellations and stars in their correct positions. The Milky Way is highlighted.
• A shared axle: This allows both spheres to rotate independently, mimicking the movements of Earth and the apparent sky.
• An angle scale: A measurement tool on the supporting frame, showing angular distances from the equator to help locate stars.
• A tilted frame: The frame holds the axle at a 23.5-degree angle, representing Earth’s tilt, which causes seasons.

This device lets users:

• Visually grasp the positions of constellations.
• See how Earth’s rotation changes the visible stars.
• Determine which stars are visible from different locations.
• Understand the reason for seasonal changes.
• Visually see the Milky Way galaxy.

Essentially, it’s a practical tool for learning about the relationships between Earth, stars, and our galaxy.
